Zac Brown Band surprises concertgoers at Boston’s Fenway Park by giving away free cruise vacations to the full crowd of about 37,000 attendees during its Aug. 2 show. Multiple outlets report the promotion is for trips on Margaritaville at Sea. The band announces the giveaway shortly before performing “Same Boat,” and frames it as a major milestone celebration linked to its run of 15 consecutive sold-out Fenway Park concerts.

Several reports estimate the total value of the giveaway at around $40 million, while others describe it as one of the largest giveaways in history. In addition to the scale of the prize, coverage notes fans leave the venue with instructions to redeem the offer.

While outlets vary in phrasing, they consistently describe the same event: a large, crowd-wide cruise giveaway at Fenway Park tied to the band’s record-setting streak and presented during the live performance. The coverage does not indicate any material change to the core details, such as the number of recipients or the cruise brand being offered.
